Abstract

Previous calculations of the γ dose given to Risø Calibration Quartz (RCQ) were performed using mass absorption and mass attenuation coefficients. In this paper, we update the γ dose given to RCQ using Geant4 simulations and provide a comparison with three other γ sources in Denmark. We also show experimental evidence that the luminescence response to a¹³⁷Cs γ irradiation is 4% higher than that resulting from a⁶⁰Co γ irradiation for the same dose, confirming the suggestions of Autzen et al. (2021) based on simulations.
